Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 189564, here are decompositions:

5 + 189559 = 189564
17 + 189547 = 189564
41 + 189523 = 189564
47 + 189517 = 189564
71 + 189493 = 189564
73 + 189491 = 189564
97 + 189467 = 189564
101 + 189463 = 189564

Showing the first eight; more decompositions exist.
